The hotel is located near Donauzentrum and near the Donau park. The parking is free. At Lenas Donau Hotel you will find a nice place to take a good sleep. The room is comfy, with all the accessories that a hotel with 3 stars should have. I visited this place in a warm winter, but the heat in the room was pleasant. The staff is well prepared and the breakfast is tasty, like in other good place. No aircon but did provide a fan and could leave the window open a little. Walls were scuffed & dirty.
